PEG-3 DISTEARATE.

Valuable CAS 9005-08-7 / SURFACTANT - EMULSIFYING

PEG-3 Distearate is a versatile ingredient primarily functioning as a surfactant, emulsifier, and thickening agent in skincare formulations. It facilitates the stable blending of oil and water phases, enhances product texture, and aids in effective cleansing.

Summary

Surfactant Emulsifying agent Thickening agent Opacifying agent Pearlizing agent Solubilizer

Science

Mechanism of Action

On the skin, PEG-3 Distearate acts as a surfactant, reducing surface tension to allow water and oils to mix efficiently, which is crucial for effective cleansing. As an emulsifying agent, it creates and maintains stable emulsions by uniformly dispersing one liquid within another. It also functions as a thickener, increasing the viscosity of formulations by swelling its molecular structure, thereby stabilizing the product's consistency. Additionally, it can contribute to the aesthetic appeal of products as an opacifying or pearlizing agent, and can act as a solubilizer for water-insoluble ingredients.

Stability

PEG-3 Distearate exhibits enhanced stability against heat and oxidation when compared to soy lecithin. However, its thermal resistance is not exceptionally high, particularly when utilized for pearlizing effects, due to its relatively low melting point which ranges from 44-51 degrees Celsius.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that PEG-3 Distearate, along with a range of other PEG Distearates, is safe for use in cosmetic formulations. While specific toxicity data for PEG-3 Distearate is limited, related compounds demonstrate low oral and dermal toxicity, minimal ocular irritation, and no evidence of mutagenicity, carcinogenicity, or reproductive toxicity. Moumoujus adheres to CIR recommendations for manufacturers to adjust formulations to mitigate potential effects, especially for products intended for use on damaged skin, and to ensure purification processes control the presence of 1,4-dioxane, a potential ethoxylation by-product.
